CLAIMS

1. A luminaire system comprising :

a first support (10) ;

a second support (20) movable with respect to said first support (10);

a moving means (30) configured for moving the second support (20) relative to the first support (10), such that a position of the second support (20) with respect to the first support (10) is changed;

wherein the moving means (30) comprises a lever (31) mounted in a rotatable manner around a rotation axis (RA), said lever (31) comprising a movable end portion (31a) configured for being rotated by a user or an actuator around said rotation axis (RA), said movable end portion (31a) being located at a distance from the rotation axis (RA); wherein the moving means (30) is further configured to convert a rotation of the lever (31) around said rotation axis (RA) into a movement of the second support (20) relative to the first support (10);

- wherein a plurality of light sources (110) is arranged on one of the first support (100) and the second support (200), and is configured to emit light through one or more optical elements (250) associated with the plurality of light sources (110) and arranged on the other one of the first support (100) and the second support (200).

2. The luminaire system according to claim 1, wherein the first support (10) comprises said plurality of light sources and the second support (20) comprises said one or more optical elements (21) associated with the plurality of light sources.

3. The luminaire system according to claim 1 or 2, wherein the rotation axis (RA) is

substantially perpendicular to the first support (10).

4. The luminaire system according to any one of the previous claims, wherein a leverage distance (LD) between the movable end portion (31a) of the lever (31) and the rotation axis (RA) is at least two times, preferably at least five times, more preferably at least ten times bigger than a maximum travel distance of the movement of the second support (20) relative to the first support (10).

5. The luminaire system according to any one of the previous claims, wherein the movable end portion (31a) is an elongate element extending in a direction substantially perpendicular to the rotation axis (RA).

6. The luminaire system according to any one of the previous claims, further comprising one or more positioning elements; and wherein the moving means (30) is configured for cooperating with the one or more positioning elements to position the second support with respect to the first support in a plurality of predetermined positions.

7. The luminaire system according to any one the previous claims, wherein the movement of the second support (20) with respect to the first support (10) comprises a translational movement.

8. The luminaire system according to any one of the previous claims, wherein the movement of the second support (20) with respect to the first support (10) comprises a vertical movement.

9. The luminaire system according to any one of the previous claims, wherein the lever (31) is coupled to the first or second support (10, 20).

10. The luminaire system according to claim 9 or 10, wherein the lever (31) comprises a rotatable shaft (37) rotatably received in a recess of the first of second support (10, 20).

11. The luminaire system according to any one of the previous claims, wherein the rotation axis (RA) of the lever (31) is fixed with respect to the first support (10).

12. The luminaire system according to any one of the previous claims, wherein the rotation axis (RA) of the lever (31) is substantially perpendicular to the movement plane of the second support (20) with respect to the first support (10).

13. The luminaire system according to any one of the previous claims, wherein the lever (31) extends through a compartment of the luminaire system such that the movable end portion (31a) can be moved from outside the compartment of the luminaire system.

14. The luminaire system according to the previous claim, wherein the lever extends (31) through a passage in a wall of the compartment, said passage being provided with a sealing means configured for sealing the passage such that water ingress is prevented.

15. The luminaire system according to any one of the previous claims, further comprising a guiding means (60) configured for guiding the movement of the second support (20) with respect to the first support (10).

16. The luminaire system according to the previous claim, wherein the guiding means (60) is integrally formed with the first or second support (10, 20).

17. The luminaire system according to the previous claim, wherein the guiding means (40) comprises a plurality of elongated guiding holes located in the first or second support (20).

18. The luminaire system according to any one of the previous claims, wherein the lever (31) comprises an eccentric element (34) cooperating with a guiding element (36) of the first or second support (10, 20), said eccentric element (34) being centered around an eccentric axis (EA) parallel to the rotation axis (RA) of the lever (31).

19. The luminaire system according to any one of the previous claims, wherein the movable end portion (31a) comprises a ferromagnetic material or a magnet (32).

20. The luminaire system according to the previous claim, wherein the lever (31) and the luminaire system are configured such that the lever (31) is rotatable by means of a magnet element or a ferromagnetic material outside the compartment (50) of the luminaire system.

21. A luminaire system assembly comprising:

a luminaire system according to claim 19 or 20;
